Description

Technical Field

[0001] The present invention relates to the field of intelligent micro-break technology, and in particular to a method and system for identifying physical connection relationships of intelligent micro-breaks. Background Art

[0002] Smart micro-break technology integrates advanced technologies such as digitalization, the Internet of Things, and cloud computing to achieve real-time monitoring and precise control of circuit status. It can monitor key parameters such as voltage, current, and power of the circuit in real time. Once an abnormality is detected, it can cut off the power supply within milliseconds to effectively protect the safety of the line and equipment. Smart micro-breaks also have intelligent monitoring and early warning functions. Through built-in high-precision sensors and Internet of Things technology, circuit data can be analyzed in real time. Once an abnormality is detected, the early warning mechanism will be triggered immediately, and early warning information will be sent to the user through the built-in communication module. Smart micro-break switch products are widely used in user-side scenarios such as parks, communication rooms, street lights, etc., to support power safety, energy efficiency management, and intelligent operation and maintenance services in the substation area.

[0003] Traditional intelligent micro-breaks are usually a control panel with a switch to control the on and off of a transmission line. At the same time, the intelligent micro-break communicates with the gateway through the bus, and the gateway issues instructions for remote data collection or remote control. Therefore, the number of micro-break switches used for control is large and the cost is high. In order to present the micro-break connection relationship diagram of the entire campus building or computer room, in many cases, the connection relationship of the micro-break switches is identified by manual input or carrier characteristic current method.

[0004] Among them, the manual input method is time-consuming and laborious, and can only guarantee the accuracy of the connection relationship between switches in the initial state. With the increase or decrease of intelligent micro-breaks, the connection relationship between switches cannot be maintained. The problem of real-time changes in switch connection relationships can be solved by the carrier characteristic current method. However, due to interference and mutual influence between branches, the recognition accuracy is not high.

[0005] As for the connection relationship of intelligent switches, some people also obtain the connection relationship of switches by turning each switch on and off and then reading the status of other switches. Although this solution is simple, the number of operations is n*(n-1)…*1=n! As the number of switches increases, the complexity increases geometrically, and it is not applicable when the number of switches is large. Summary of the invention

[0006] The present invention provides an intelligent micro-break physical connection relationship identification method and system, which are used to solve the defects of low efficiency and low precision in the prior art of micro-break switch connection relationship identification, thereby improving the recognition efficiency of micro-break switch connection relationships and improving the connection relationship identification accuracy.

[0017] When the switch of the other intelligent micro-breaker recognizes that the signal strength of the characteristic current is greater than the first preset threshold and the background noise is less than the second preset threshold, it is determined that the switch of the other intelligent micro-breaker is connected to the selection switch in the current switch.

[0018] According to the recognition result of the switch of the other intelligent micro-breaks for the characteristic current, the preset condition is that the number of parent switches of each switch in the to-be-identified intelligent micro-breaks is less than 2, and when the connection relationship between the switches in the to-be-identified intelligent micro-breaks does not meet the preset condition, the connection relationship is corrected, including:

[0019] If there is a first switch with multiple parent switches in the connection relationship, it is determined whether each parent switch is the final parent switch of the switch in question according to the on-off state of the switch in question when the on-off state of each parent switch of the first switch is off.

[0020] According to the recognition result of the switch of the other intelligent micro-breaks for the characteristic current, the preset condition is that each switch in the to-be-identified intelligent micro-breaks has a connected switch, and when the connection relationship between the switches in the to-be-identified intelligent micro-breaks does not meet the preset condition, the connection relationship is corrected, including:

According to the identification result of the characteristic current of the switch selected again, the switch that is connected to the second switch is determined.

[0028] Query the relationship correspondence table to obtain the switch mounted under the current intelligent micro-break.

[0046] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] Combine the following Figure 1 A method for identifying physical connection relationships of intelligent micro-breaks of the present invention is described, comprising:

[0048] Step 101, selecting a single switch from switches mounted under the current smart micro-breaker in the smart micro-breaker to be identified, and sending a characteristic current to the selected switch in the current smart micro-breaker through a sending component in the current smart micro-breaker;

[0049] Step 102, obtaining recognition results of the characteristic current by switches of other intelligent micro-breaks among the intelligent micro-breaks to be identified except the current intelligent micro-breaks;

[0050] Step 103, determining the connection relationship between the switches in the to-be-identified intelligent micro-breaks according to the identification result of the characteristic current of the selected switch in the to-be-identified intelligent micro-breaks;

[0051] Step 104: When the connection relationship between the switches of the to-be-identified intelligent micro-breaks does not meet a preset condition, the connection relationship is corrected.

[0052] The smart micro-break network mainly includes two main devices, the multi-service gateway and the smart micro-break. The two main devices are connected to the multi-service gateway and the last-level smart micro-break respectively. The multi-service gateway runs the topology identification APP to realize the control and calculation logic functions. As an execution unit, the smart micro-break receives commands from the multi-service gateway, starts the characteristic current identification function, and generates characteristic small current as needed. Each smart micro-break is mounted with one or more switches. Multiple switches under the same smart micro-break are connected in parallel.

[0053] like Figure 2 As shown, four composite switch-type intelligent micro-breaks form a topology through upper and lower interconnection, where micro-break 1 (including switch 1 and switch 2) is the first level, micro-break 2 (including switch 3, switch 4, switch 5 and switch 6) and micro-break 3 (including switch 7 and switch 8) are the second level, and micro-break 3 (including switch 9 and switch 10) is the third level.

[0054] The multi-service gateway sends a topology identification command to all the intelligent micro-breaks to be identified {K1, K2, K3…} to start topology identification. The multi-service gateway selects a switch for each intelligent micro-break to be identified and controls the sending component in each intelligent micro-break to be identified to send the characteristic current serially. After sending the characteristic current to the previous intelligent micro-break to be identified and completing the identification, the characteristic current is sent to the next intelligent micro-break to be identified. The multi-service gateway also records the time point when the characteristic current is sent by name. This time point is used for subsequent topology result comparison and analysis.

[0055] For example, select switch S1 for MCB K1 and send a command to switch S1, calling switch S1 to send the characteristic current. After a period of time, such as 30 seconds, poll MCB K2, select switch S4, and call switch S4 to send the characteristic current. The duration of the characteristic current sending can be about 9.6s. You can delay 30s to wait for the characteristic current identification to be completed and query the identification result. Call the next intelligent MCB to be identified at any time until all the intelligent MCBs to be identified, K1 to Kn, are identified.

[0056] The switches of other intelligent micro-breaks except the current intelligent micro-breaks in the intelligent micro-breaks to be identified identify the characteristic current to obtain the identification results. The multi-service grid analyzes the identification results returned by the micro-breaks to obtain the connection relationship between the switches of the micro-breaks. If the first round of identification results are correct, the topology identification process ends and the topology identification results are output.

[0057] When the connection relationship between the switches to be identified does not meet the preset conditions, it indicates that there is signal interference, and it is determined that there is a suspicious switch. A characteristic current is sent to the suspicious switch to re-identify the connection relationship, or the accurate connection relationship is determined by turning off the switch.

[0058] This embodiment first uses the characteristic small current method to quickly identify a relatively accurate smart micro-breaker connection relationship diagram, and then uses the switch characteristics of the smart micro-breaker to determine the accurate connection relationship for the questionable connection relationship. Moreover, for the composite switch type smart micro-breaker, only a single switch is selected from each micro-breaker for characteristic current identification, thereby improving the recognition efficiency and accuracy of the smart micro-breaker connection relationship.

[0059] On the basis of the above embodiment, in this embodiment, according to the identification result of the characteristic current of the selected switch in the intelligent micro-break to be identified, determining the connection relationship between the switches of the intelligent micro-break to be identified includes:

[0060] According to the recognition result of the characteristic current by the switch of the other intelligent micro-breaker, it is determined that the switch of the other intelligent micro-breaker is connected to the selection switch in the current switch;

[0061] Determine the number of switches connected to the selection switch in each intelligent micro-break to be identified when sending characteristic current to the selection switch;

[0062] According to the number of switches with a connection relationship that have been identified corresponding to the selection switches in the intelligent micro-breaks to be identified, the level of each intelligent micro-break to be identified is determined, and the lower the number of switches with a connection relationship that have been identified, the higher the level;

[0063] A switch in an upper layer of each intelligent micro-break to be identified that is associated with a selection switch of each intelligent micro-break to be identified is used as a parent switch of the switch in each intelligent micro-break to be identified.

[0064] Under normal circumstances, when the characteristic current is sent to the selection switch of the current smart micro-breaker, the characteristic current is transmitted upward, and only the smart micro-breaker in the upstream direction of the current smart micro-breaker switch can recognize the characteristic current, while the smart micro-breaker in the downstream direction cannot recognize the characteristic current, thereby determining the switch that is connected to the selection switch.

[0065] For example, Figure 2 When switch 7 in the intelligent micro-breaker 3 sends the characteristic current, the identification module in switch 1 of the intelligent micro-breaker 1 can identify the characteristic current, while the switches in the intelligent micro-breakers 2 and 4 cannot identify the characteristic current, so it is determined that switch 1 and switch 7 are connected.

[0066] After sending characteristic currents to the selection switches in all the intelligent micro-breaks to be identified for identification, the number of switches connected to the selection switches is determined when the characteristic currents are sent to the selection switches in each of the intelligent micro-breaks to be identified, thereby determining the switch hierarchy and the connection relationship between the switches.

[0067] For example, a characteristic current is sent to switch 1 selected in smart micro-breaker 1, and no switch can identify the characteristic current, and the number of switches connected to switch 1 is 0. A characteristic current is sent to switch 4 selected in smart micro-breaker 2, and switch 1 in smart micro-breaker 1 can identify the characteristic current, and the number of switches connected to switch 4 is 1. A characteristic current is sent to switch 7 selected in smart micro-breaker 3, and switch 2 in smart micro-breaker 1 can identify the characteristic current, and the number of switches connected to switch 7 is 1. A characteristic current is sent to switch 9 selected in smart micro-breaker 4, and switch 7 in smart micro-breaker 3 and switch 2 in smart micro-breaker 1 can identify the characteristic current, and the number of switches connected to switch 9 is 2.

[0068] The intelligent micro-break 1 to which switch 1 with a switch number of 0 belongs is taken as the first level, the intelligent micro-break 2 to which switch 4 with a switch number of 1 belongs and the intelligent micro-break 3 to which switch 7 belongs are taken as the second level, and the intelligent micro-break 4 to which switch 9 with a switch number of 2 belongs is taken as the third level. Since switch 4 is connected to switch 1 in the first level, switch 1 is the parent switch of the switch under intelligent micro-break 2. Since switch 7 is connected to switch 2, switch 2 is the parent switch of the switch under intelligent micro-break 3. Since switch 9 is connected to switch 7 in the second level, switch 7 is the parent switch of the switch under intelligent micro-break 4.

[0069] On the basis of the above embodiment, the recognition result in this embodiment includes signal strength and background noise. According to the recognition result of the switch of the other intelligent micro-break for the characteristic current, it is determined that the switch of the other intelligent micro-break has a connection relationship with the selection switch in the current switch, including:

[0070] When the switch of the other intelligent micro-breaker recognizes that the signal strength of the characteristic current is greater than the first preset threshold and the background noise is less than the second preset threshold, it is determined that the switch of the other intelligent micro-breaker is connected to the selection switch in the current switch.

[0071] In addition to signal strength and background noise, each topology recognition result also includes the time when the characteristic current is sent and the switch address that detects the characteristic current, which is used to determine which switch of the micro-break detects the characteristic current sent by the switch and to draw the final micro-break connection relationship diagram.

[0072] On the basis of the above embodiment, the preset condition in this embodiment is that the number of parent switches of each switch in the to-be-identified intelligent micro-break is less than 2. When the connection relationship between the switches in the to-be-identified intelligent micro-break does not meet the preset condition, the connection relationship is corrected, including:

[0073] If there is a first switch with multiple parent switches in the connection relationship, it is determined whether each parent switch is the final parent switch of the switch in question according to the on-off state of the switch in question when the on-off state of each parent switch of the first switch is off.

[0074] For the micro-disconnection of composite switches, since there are multiple switches in each micro-disconnection, if each switch is required to perform a topology relationship identification, it will inevitably increase the entire connection relationship identification cycle, causing great inconvenience to operation and maintenance. Assuming that the number of switches is n1, it is estimated that it takes 30 seconds for each switch to send the characteristic current and identify the characteristic current, and the entire identification process takes about n1*30 seconds.

[0075] In this embodiment, the first round of preliminary confirmation of the connection relationship through characteristic current takes about 30*n2 seconds, where n2 is the number of intelligent micro-breakers, and the accuracy is above 90%. The remaining switches that failed to be identified are usually identified as having two or more parent switches, resulting in doubts about the connection relationship.

[0076] At this time, disconnect the parent switches of the questionable switch to confirm the connection relationship of the questionable switch. This operation takes an average of Where m is the number of intelligent micro-breakers to which the remaining 10% of questionable switches belong, p i is the number of parent switches of the questionable switch in the i-th intelligent micro-breaker.

[0077] For example, the connection relationship output by the characteristic current method is analyzed to identify the suspicious switches and their parent switch list {(S1:S1u1,S1u2),(S2:S2u1,S2u2)…(Sm:Smu1,Smu2)}.

[0078] For the doubtful switch S1, disconnect its parent switch S1u1, and detect the on / off state of the doubtful switch. If the switch S1 is also in the off state, then S1u1 is confirmed to be the parent switch of S1. Otherwise, continue to disconnect S1u2, and so on. Until the connection relationship is confirmed. Actual tests show that after this operation, the accuracy of micro-break connection relationship recognition reaches more than 99%.

[0079] This embodiment uses a characteristic small current method and a switch on-off detection method to quickly realize the automatic identification of the connection relationship between the intelligent micro-breaks in the park building or computer room, which not only greatly reduces the time for connection relationship identification, but also greatly improves the accuracy of connection relationship identification. According to the connection relationship of the intelligent micro-breaks (switches), it provides strong support for the subsequent accurate positioning of faults, solving the overload of power facilities, and solving the three-phase imbalance business, thereby achieving the ultimate goals of power safety, energy saving and efficiency improvement in places such as residential buildings and office buildings, and helping to realize the remote operation and maintenance of smart parks or smart computer rooms.

[0080] On the basis of the above embodiment, the preset condition in this embodiment is that each switch in the to-be-identified intelligent micro-break has a connected switch. When the connection relationship between the switches in the to-be-identified intelligent micro-breaks does not meet the preset condition, the connection relationship is corrected, including:

[0081] If there is a second switch in the connection relationship that is not connected to any switch, a single switch is selected again from the intelligent micro-breaker to be identified to which the second switch belongs to send a characteristic current, and an identification result of the characteristic current of the switch selected again is obtained. According to the identification result of the characteristic current of the switch selected again, the switch that is connected to the second switch is determined.

[0082] If some switch connections are not identified in the first round, it means there is signal interference, then the second round of identification process is started for the unidentified switches, and the relationship identification steps are repeated. If some switch connections are still not identified, the third round of identification is performed until the preset number of executions is reached.

[0083] On the basis of the above embodiment, in this embodiment, the identification result of the switch of other intelligent micro-breaks except the current intelligent micro-breaks in the intelligent micro-breaks to be identified for the characteristic current is obtained, including:

[0084] The signals after the switches of other intelligent micro-breaks except the current intelligent micro-breaks among the intelligent micro-breaks to be identified modulate the characteristic current are obtained, and the identification results are obtained from the modulated signals.

[0085] OOK modulation can be used to represent the "1" and "0" of the digital signal by the presence or absence of the characteristic current. The modulation carrier frequency f1 is the switching frequency of the characteristic signal. After the original information is modulated, the signal is:

[0086]

[0087] Where A represents the characteristic current amplitude, and DUTY represents the duty cycle of the characteristic signal. The modulation carrier frequency is f1, and the duration of each bit is the set bit width time. If the bit is 1, the frequency f1 is used for modulation during the bit duration; if the bit is 0, no modulation is performed.

[0088] The modulation carrier frequency may be f1=833.3Hz by default, and the duration of each bit may be 0.6s. The peak value of the characteristic current sent by the sending component should not be greater than 0.60A, and the effective value of the characteristic current when the characteristic code bit sent is 1 should not be less than 0.21A.

[0089] On the basis of the above embodiments, before selecting a single switch from the switches mounted under the current smart micro-break in the to-be-identified smart micro-break, the present embodiment further includes:

[0090] Searching through the carrier module built into each intelligent micro-break to be identified, obtaining the switch mounted under each intelligent micro-break to be identified and the address of the switch;

[0091] Registering each intelligent micro-breaker to be identified according to the address of the switch under each intelligent micro-breaker to be identified;

[0092] According to the MAC address of the carrier module and the registered address of the switch, a corresponding relationship table between the to-be-identified intelligent micro-break and the switch is established;

[0093] Query the relationship correspondence table to obtain the switch mounted under the current intelligent micro-break.

[0094] The carrier module is built in the intelligent micro-break to be identified. After the intelligent micro-break to be identified is started, the carrier module automatically searches the table to detect all switches under the micro-break and caches the switch address for registration.

[0095] The intelligent micro-break to be identified registers the switch with the intelligent gateway through the MINI carrier module, and registers all switch addresses found under this micro-break to the multi-service gateway.

[0096] After successful registration, the corresponding relationship table between the micro-break and the switch is automatically established according to the carrier module MAC registered by the agent and the registered switch address, such as {(K1:S1,S2); (K2:S3,S4,S5,S6); (K3:S7,S8); ...}.

[0097] The multi-service gateway sends a topology identification command to all MCBs {K1, K2, K3…} to start topology identification. The multi-service gateway queries the correspondence table between MCBs and switches, and sends the characteristic current by name. No matter how many switches a MCB has, it only needs to be named once.

[0098] The workflow diagram of intelligent micro-break physical topology automatic identification is as follows Figure 3 The multi-service gateway runs the topology identification APP to implement control and calculation logic functions, including: intelligent micro-break (switch) registration; accurate time calibration to ensure that all micro-breaks and switches in the area are consistent, maximizing the accuracy of characteristic current identification; starting characteristic current identification; calling the intelligent micro-break to send the characteristic current; the on-off operation of the suspected switch; and analysis and calculation of the identification results.

[0099] Each intelligent micro-breaker to be identified has a built-in MINI carrier module, a characteristic current sending component and an identification module. It first uses the characteristic small current method to quickly identify a relatively accurate intelligent micro-breaker connection relationship diagram, and then uses the intelligent micro-breaker switch characteristics to determine the accurate connection relationship for the questionable connection relationship by switching off the switch, thereby achieving good results in improving identification efficiency and accuracy.

[0100] On the basis of the above embodiments, before the sending component in the current intelligent micro-break sends the characteristic current to the switch selected in the current intelligent micro-break, the present embodiment further includes:

[0101] The time of the intelligent micro-break to be identified is calibrated so that the clocks of the intelligent micro-break to be identified are consistent.

[0102] The intelligent micro-break physical connection relationship identification system provided by the present invention is described below.
